OptiFine

OptiFine is a Minecraft optimization mod for your Windows PC! It allows Minecraft to run faster and look better with full support for HD textures and many configuration options. Enjoy!

OptiFine HD Ultra has the most optimizations and features that can increase FPS. OptiFine Standard is more compatible with other mods. OptiFine Light may be more helpful for underpowered laptops and notebooks, but it does not have any advanced features and is not compatible with ModLoader and Forge.

It comes with many optimizations that should increase the FPS without any configuration. You can further increase the FPS by configuring the Video Settings and finding the trade-off between quality and performance that works best for you.
